Specification of Letters Patent.

Application filed April 6, 1905. Serial No. 254,130.

Patented March 27, 1906.

-T all whom it may concern.-

- type.

Be it known that 1, CHARLES J. EWART, a citizen of the United States, residing at Roscoe, in the county of Sullivan and State of New York, have invented a new and useful Improvement in Road-Sweepers, of which the following is a specification.

This invention relates to a sweeper for macadam roads adapted to be attached to the rear end of a road-roller and provided with reversible and interchangeable brushes.

The invention consists in the novel features of construction and combination of parts hereinafter described, pointed out in the claims, and shown in the accompanying drawings, in which Figure 1 is a side elevation showing the brushes in position for forward movement of the roller. Fig. 2 is a similar view showing the position ofthe brushes when direction of the roller is reversed. Fig. 3 is a plan view of my device, the sweeper being shown detache'd.

In the drawings, A represents the coal-box or rear end portion of a road-roller of any To the vertical corners of this end portion are secured brackets A, in which is j ournaled the yoke portion of a U-shaped tubular frame B. A shaft 0 is rotatably journaled in suitable sleeves or bearings carried by the free ends of the frame B, and the frame is normally held in a horizontal position by means of chains B, connected at their upper ends to the -rear of the roller, or, more properly, the coal-box of the, roller, and at their lower ends to sleeves loosely fitting on the shaft 0. Each chain, two being shown by me, is cut and a spring B interposed between its two end portions for the purpose of taking up the jar of the roller. On the shaft 0 are placed loosely a plurality of sleeves C" and G arranged in alternating pairs, the sleeves of each pair being spaced apart. To each sleeve C is connected an end of a rod D, and to each sleeve C 'is connected a rod E, the rods D making a greater angle with respect to the shaft 0 than the rods E. As has been stated, the sleeves O and O are arranged in pairs, and the rods D, connected to each pair of sleeves C converge, and the rods E, connected to apair of the sleeves 0 also converge, the forward ends of each pair of rods D being secured ina socket-block D, while the forward or downward ends of each pair of rods E are connected to a socketlock E. These socket-blocks carry plates D and E respectively, forming clampingplates, and coacting clamping-plates D and E respectively, are secured to the clampingplates D and E by rods or bolts D" and E provided with suitable set screws. Be-

tweeneach pair of coacting plates are clamped plates D or to the two outermost ones are secured metal segments G, forming rockers which serve to support the weight of the frame B when the brushes are reversing, and

ghese rockers may be two or more in num- When the roller is moving forwardly, the

brushes occupy the position shown in Fig. 1,

half of the brushes carried'by the rods E being in engagement with the road-bed and in advance of the same number of brushes carried by the rod D, the segments G being clear of the ground and all of the brushes being to the rear of the shaft 0. When the roller is reversed, instead of pushing the brushes backward the frame B is lifted by the rods D-and E, which assume a perpendicular position, the weight being at this time supported by the rockers G instead of falling on the brushes F, and as the rearward movement continues the shaft *0 passes above the brushes and they rest beneath the frame B, the

brushes F which had been out of engagement with the road on forward ,movement of the roller being nowinengagement with the roadbed and being drawn rearwardly from the shaft 0. Y

- It will be obvious that the sweeper herein described may be connected to any wheeled truck and is not'limited in its use to the combination with a road-roller.

Having thus fully described my invention, what Iclaim as new and patentable, and desire to secure by Letters Patent, is

1. A road-sweeper, comprising a verticallymovable frame, a rod pivotally connected at one'end to the said frame, and brushes car,- ried adjacent the free end of the rod, the said brushes projecting in different directions so that one of said brushes contacts with the ground during movement of the sweeper in one direction and the other brush contacts with the ground when the rod is swung upon its pivot-point and the sweeper is moved in the opposite direction.

2. The combination with a wheeled truck, a U-shaped frame pivotally carried at the rear of the truck, a shaft carried by the frame, rods pivotally mounted on the shaft, clamp ing-plates carried by the rods, and a pair of brushes at an angle to each other carried by the plates.

3. The combination with a wheeled truck, of a U-shaped frame, chains adapted to normally hold the frame in a horizontal position, rods in pairs pivotally supported from the frame, said rods being arranged in sets, one set being in advance of the other set, coacting forth.
